It's that time of year again. Time when your local market entrances are flooded with Girl Scouts selling boxes of Samoas, Tagalongs and Thin Mints. But one 13-year-old Girl Scout in San Francisco and her mother made a rather business-savvy decision to sell cookies outside of a medical marijuana dispensary.

On Monday, Danielle Lei and her mother set up shop outside the Green Cross store with the cookies. With the store's blessing, Lei sold 117 boxes in two hours.

Holli Bert, a spokeswoman for the Green Cross, said that after just 45 minutes, Lei had to call for backup cookies to replenish her stock.
